My skipper (who doesn't have a computer) sailed a H20 in the Around the Island years ago and had "sailed the two worst storms of my life on the same day". He said that there was lighting striking everywhere and no one was hit that day. He also told me of a regatta where everyone was scrambling to get boats settled on the beach when a storm came up and lighting struck the beach. Anyone who was touching metal was shocked. He himself was one. He is convinced that sailing in lighting is fine. I don't think I really want to give it a try.
